- Patented Feb. 13, 1906 Application filed August 31,1905. Serial llo.276,562.

To all whom' it may concern;

Be it known that l, MANUEL GONZALEZ BABIO, a subject of the King ofSpain, and a resident of the city of New York, borough of Brooklyn, inthe county of Kings and State I of New York, have invented a new anduseful Improvement in Vehicle Wheels, of which the following is afull,clear, and exact description.

My invention relates to an improvement in vehicle wheels, andparticularly to an improvement in the construction of the wheel forwhich I have made an application for patent, filed March 6, 1905, SerialNo. 248,479,

and the purpose of the invention is to avoid,

friction between the flanges of the primary hub and the sides of thesecondary hub, so as to adapt the above-named construction in the mostsatisfactory manner to light and .highgrade vehicles, which adaptationwill give more comfortto their occupants than that attainedin vehiclesnow in use, and this is accomplished by changing the sha e andconstruction of the pneumatic tube ocated between the primary and thesecondary hubs, providing said tube with an inner chamber which has aneccentric relation in cross-section to the circular iexterior outline ofthe tube,-and in further providing the pneumatic tube with an integralrim at the exterior face of its inner portion, the said rim being adated to enter an annular pocket at the exterior of a check or guidingcollar mounted loosely upon the primary hub, the outer and theme nerportions of the side surfaces of the said pneumatic tube fitting snuglywithin the secondary hub, which hub has limited play to and from thetension'takes p ace in direction of the rim of the pneumatic tube suchtension overcomes to a certain extent the tension which will take placeat the sides of the tube and whereby also the pneumatic tube will bekept substantially in normal shape when it is inflated, and at the sametime the tube will work without undue lateral motion, as the wall inthechamber in the secondary hub receiving said pneumatic tube is more orless rooved or s errated'in order that it may be eld firmly {to said hubby means of exterior ribsformedlin the pneumatic tube and coincidjngwiththe grooved or serrated portion of "theliub whenthe tube is inflatedwith air. The invention consists in the novel conrimary hub, wherebywhen "struction and combination of the several parts, as will be.hereinafter fully'set forth, and pointed out in the claims.- Referenceis to be had to the accompanying drawings, forming a part of this secification, in which similar characters of re 'erence indicatecorresponding parts in all the figures.

Figure 1 is a. vertical section through the hubof the improved wheel,the section being takensubstantiallyon the line 11 of Fig. 2, Fig. 2'isa vertical section through the hub of the wheel, the section being takenat right; angles to that shown in Fig. l and on line 2 2 of Fig. 1; andFig. 3 is a section corresponding to the section shown in Fig. 2 andtaken through the hub of a wheel slightly modified in form. p i Arepresents the primary hub of the wheel,

to turn around the primary hub, being separated therefrom apredetermined distance. The primary hub is provided with a taperin bore10 to receive the spindle of an axle, an

hub A an annular flange 11 is exteriorly produced, said flange havinganannular concave roove 11 in its outer face, as is shown in ig. 2." Theopposite or outer end of the primary hub A is provided with an exteriorthread 12, and between the center of the primary hub and the said-threada flange 13 is he ed or otherwise secured on said primary huh facing theflange 11.. These two flanges l1 andv lfiiiarsnet in contact with thesecond* which lies hptween them, there being; for example, a space orclearance of one-sixteenth and the-secondary hub, andsaid flanges 11-and 13 may e properlydenominated the heads for t e primary .hul'i iinehead be- Sing stationary and the other removable. The removable head13is held-in position on the hub A by suitable nuts 14 and 14, screwedupon its threaded portion 12. The head 13 is provided with an annularoutwardly-ex tending marginal flange 13 for a purpose to be hereinafterdescribed. j

A. collar 15 is mounted to turn on-the primary hub A between the heads11 and 13, having slight play in direction of said heads for example, aneighth or a sixteenthof an mentioned as e isting betweeii theheads ll,

Thiscollar may be termed a check of guiding collar, since itwill in thelatter case, in connection with the pneumatic tube,

be required:

A pneumatic tube-C is located between the two-hubs A and B employed inconnection with the collar 15, intervening between the rimary hub andthe said pneumatic tiilj'e, the atter being .1161 portion, graduallydiminishing in width-pr osition the primary hub in relation to theateral motion that willtake place when the ing limited to the space orclearance between theheads 11 and 13 and the secondary hub. .Thecollar-.15 is provided .with two annular side of the center, and the"space between these Y ribs constitutes a ticket where the pneumatic tubeC engagesthe secondary hub B Said ribs-16 are prefer orm. Thus in thepneumatic said tube, as is clearly'shown inF'ig. 2.

At the inner central portion of the pneumatic tube C a rim or an annularflange is formed integral with. the tube, lar flange or rim 0 is adaptedtoenter the space between he annular ribs 16 on the selflar 15. When thesecondary hub is fitted in position relative to the primary hub, it haspractically the same play between the heads 11 and 13 on the primary hubas does thecollar 15 of the latter; but, as stated above, if in practiceit eral play of the collar between be avoided by making enough to turnin contact with the heads. s aceis normally t e inner face of neumatictube and the bottom formed between the ribs16, as is illustrated inFigs;2 and 3:

The secondary is provided with an annular outer section 27', which isintegral with the body 17 and in the: periphery of this outer section 27an annular groove 28 is formed, the sides whereof taper inward indirection of each other, and the said groove 28 isadapted to receive theinner def that-they may not do any harm to said pneumatic tube, as isclearly "shown in Figs. 12 and:3.=

The .body 17 0f the secondary hub B -is of on each side between theinner edge of'th'e said-secondaryhub? and the collar 15, I 2 and 3,andin the inner'face'of the body' of said secondary hub B' -an' annularchamber 19 isformed, whose. sidewalls are straight, the outer wall ofsaid chamber being arched or semicircular in foru 2 and 3. In the sidewal -ls ofthe-said chamber 19, adjacent to' theouter wall of saidchamber, grooves or serare preferablymadp, said. groovesor serrationsbeing annular. t may herebe the said 'collar long vided by .thepneumatic tube, forming annueach sidein conneumatic tube, as will beexplained hereinafter, which spaces are des- I s as 19". In the furtherconstruction of t e bod portion 17 of the secondary hub an annu arflange 21 is made at its outer side face, as is shown in Fig. 2, and, asis also shown in the same figure, another flange 24 is produced at theopposite or inner'side face of-sa'id secondary hub, extending at a rightangle from the hub and then inward in direction of the flange 11 of theprim'ary'hub'. This inner flange 24 is provided with an exteriorannular/flange 25, extending from its inner face.

' Under the constrdction shown ih Fig. 2 the primary and the secondaryhubs and B are connected at their inner "portions by chains portion,there being one spaceat are held in position by spacin -blocks 30. Inthe outer or peripheral wall 0 the chamber in the secondary hubB'apertures 28 are made, leading into the groove or trough28, as shownin. Fig. 1, and adapted to receive likewise shown in Fig. 1, which boltspass vided with suitable nuts at their outer ends.

A dust-guard 31, made of any suitable ma- -.terial, preferably a pliablematerial, is secured to the outer resting-the inner edges of said theflange 21 at the outer face 0 the second-' ary" hub and against theunder face of the outer flange 13 of the head and the other rearwardly;

I

The pneumatic tube 0 is provided with an opening 32, exteriorlysurrounded by a boss 32, integral with said tube,- and the stem 33 of aninflating-valve is passed through said opening 32*, which stem at itsinner end is provided with an integral disk 34, through which the stemis carried, and this disk 34 engages with the inner face of saidpneumatic tube, as shown in Fig. 1. The outer end of the stem 33 isthreaded to receive a nut 33, and a sleeve 35 is passed over the stem33. Said sleeve 35 is rovided at its lower end -with an integral risk36, which receives the boss 32 and which connects with the outer face ofsaid pneumatic tube immediately over the inner disk 34. The said sleeve35 and the stem 33 are carried out through a suitable aperture in theperipheral wall of the chamber of the secondary hub and out through aspacing-block. The outer end of the sleeve 35 is'exteriorly threaded toreceive a nut 37, so that this sleeve serves the same purpose as a bolt29 and. likewise protects the stem of the valve, and in tightening upthe nut 33 against the sleeve 35 the pneumatic tube is firmly boundbetween the two disks 34 and 36; A suitable'cap 38 is provided for theouterend of the valve-stem 33.

The construction shown in Fig. 3 is practically the same as that shownin Fig. 2, but the size of the parts are somewhat reduced, so as torender the combination made by the primary and secondary hubs of thewheel lighter and more compact. The operation.

I of the combination of hubs shown in Fig. 3 is identical with theoperation of the combination of hubs shown in Figs. 1 and 2. Thedifference consists in the sha e of the secondary hub shown in Fig. 2, wich is made with round shoulders projecting on its sides, while thesecondary hub B (shown in Fig. 3) has no round shoulders and is madeconsistent in width throughout. The said'diflerence further consists inthe fact that the chains 26" are employed to connect the two hubs A. andB at both their inner and outer sides, the chains at one side extendingin one direction and the chains on" the other side in an oppositedirection, andithe secondary hub Bis rovided at each side of its outermargin wit 1 an annular flange 39, having an inwardly-extending member.The outer [ends of the chains 26 are attached to these flanges. The

dust-guards 4:0 and a are attached to the heads 11 and 13 in practicallythe same manner as under the construction shown in l igl 2, but aresecured to the secondary hubB by suitable rings 42, which clamp thematerial of the dustguards to the outer peripheral marginalisurfaces ofthe flanges 39.

The ribs 16 are made rounded in order that the collar 15 may not do anyharm to the pneumatic tube (1. By reason of the peculiar formation ofthe pneumatic tube and the coacting ribbed collar 15 and since theairressure in the tube C acts about the same- -111 all directions whenthe rim or flange c of the said neumatic tube is forced toward the ocret'forrned by the ribs lfithe tension ta ring place in this directionwill overcome to a great extent the tension that would otherwise besustained at the sides of the pneumatic tube C. In practice the twoperipheral ribs 16 will be placed. at the proper distance one from theother, so as to attain equilibrium of tension caused by the air-preasure acting on the portion of the pneumatic tube opposite to the pocketand the pressure acting on the adjacent sides of said. pneumatic-tubeportion, and thus the equilibrium referred to will be obtained, and atthe same time the pneumatic tube will keep its normal shape as far as itis practically desired when it is inflated with air. It is understoodthat in practice the normal dimensions of the said pneumatic tube willbe calculated so as to obtain the greatest expansion or dilation causedby the air-pressure at its inner portion when said tube is inflated withair at the required )ressure, whereu on said inner ortion will be incontact wit the ribs 16 of t e collar 15 to the required degree oftightness, and under these conditions the pneumatic tube will workwithout undue lateral motion. To further secure this latter object, thegrooves 20 are made n the chamber 19 of the secondary hub, and y thesemeans when the tube C is inflated the pressure-forces the rubber 'ofthetube into the said grooves, and in thismanner annular ribs are formed inthe pneumatic tube by means of the air-pressureactin to" ward thegrooves made in the secondary nub, and thus the pneumatic tube isheldsofir'mly in the secondary hub that no undue lateral motion at itslower or interior portion can take place, there being am le room forexpansion and contraction oi said tube C to take place in the annularchambers 19 and the space or pocket between the ribs 16 of the collar15. he space between the inner edge of the secondary hub and the collar15 allows free eccentric play of the primary hub to and from thesecondary hub, and thespace or clearance between the heads 11 and 13 andthe sides of the secondary hub avoids all friction between these partsas far as practically IIO erases with annular grooves,
